There's no reason they shouldn't work since there are no 64bit executables. So even if you are running a 64bit OS the game will still be 32bit.I've used one of these trainers in the past myself (the 1.5.04 version I believe). That worked fine on the 64bit version of Windows Vista.

I have Vista 64 bit. my game work untill i gonna to the loading screen when you start a new game, i think it is the traner 1.5.07 and i also use steam verson of clear sky, it workt over half a year a go perfectly, i wonder if i reinstall the gam,e so it can update to 1.5.08, and this problem mite be fixt
